Abstract: In the audible-tone and voice announcement generator according to the invention, several counting devices operating independently of one another are provided which continuously generate addresses in accordance with their respective switching position. These addresses are offered to the addressing inputs of a programmable read-only memory via a multiplexer. In this arrangement, a storage cell is first selected within each time slot during a first phase, which cell provides information on what type of audible tone or voice announcement is to be sent out in this time slot. During a second phase within the same time slot, a storage cell is selected with the aid of the information read out in the first phase and in accordance with the position of a sampling counting device, from which cell the PCM word to be output at this time is read out. <IMAGE>

Abstract: A butt connection for pipe lengths (1, 2) which consist of two concentric pipes of different diameters (outer and inner pipe 3 and 4), and carry in particular exhaust gases and combustion air from gas burners, comprises at least one axially movable collar (5), which connects the inner pipes (3) of these pipe lengths (1, 2), bridges a gap (a or b) existing between the end faces of the pipe lengths (1, 2) and consists of two sections offset with respect to one another, one of which has an internal diameter corresponding to the external diameter of one of the pipes (3, 4) and the other has an external diameter which corresponds to the internal diameter of one of the pipes (3, 4). The minimum length of one of the two sections corresponds to the maximum gap of the end faces of the two pipe lengths (1, 2) to be connected to one another. As a result of this dimensioning, a pipe length (2) which is initially movable can be guided onto a fixed-position pipe length (1) in a direction at right angles to the latter's axis and can then be connected to this fixed-position pipe length (1) simply by axially moving the collar (5). <IMAGE>

Abstract: In a charging control apparatus for a vehicle for controlling generation of electric power from a vehicle's generator charging a battery, the rate of increase in field current supplied to the generator is increased when an electrical load is connected to the generator. A switch is connected in series with the field winding, and a conduction rate detector detects the conduction rate of the switch and generates an output signal having a value which is a function of the conduc­tion rate of the switch. A maximum signal generator generates an output signal having a value larger by a predetermined value than that of the output signal of the conduction rate detector, and a comparator is enabled to operate while the maximum signal generator is generating the maximum signal. The comparator is preferably enabled again when the value of the output signal of the conduction rate detector exceeds a setting. The predetermined value is preferably increased with the increase in the conduction rate of the switch. By enabling the comparator depending on the value of the maximum signal, the conduction rate of the switch can be gradually increased after it is increased by a predeter­mined value. The comparator is enabled when the value of the output signal of the conduction rate detector attains its setting, and the battery can be quickly charged when the conduction rate exceeds the setting. Because the predetermined value is increased with the increase in the   conduction rate, the battery can be quickly charged according to the conduction rate while decreasing the burden on the engine.

Abstract: According to the present invention, prior to evaporation treatment of a ruthenium-containing nitric acid solution (2), ruthenium ions in the nitric acid have been converted into a nitrosyl ruthenium complex compound in which nitro group (NO₂) is coordinated and the thus pretreated ruthenium-containing nitric acid is supplied to an evaporation apparatus (9). When the nitric acid solution (2) where ruthenium is in the form of a nitrosyl ruthenium complex compound in which nitro group is coordinated is supplied to the evaporation apparatus (9) the nitro group coordinated in the nitrosyl ruthenium complex compound is replaced with nitrato group. During this replacement, oxidation-reduction potential of the nitric acid solution (2) is kept low while release of nitro group continues and oxidation decomposition of ruthenium nitrosyl nitrato complex and oxidation into ruthenium tetraoxide as a final product are inhibited and thus volatilization of ruthenium is inhibited.

Abstract: Optical conductors exhibit in most cases optical waveguides (1) which are accommodated loosely and with excess length in a protective sheath (2). Changes in length which are due to temperature fluctuations lead to increased attenuation losses, since the coefficients of thermal expansion of the optical waveguide (1) and the protective sheath (2) differ very greatly. If the protective sheath (2) is wound round in a helix configuration with a stiff supporting band (3), the protective sheath (2) is deformed in a helix configuration and the protective sheath (2) and supporting band (3) are rotated about one another, whereby a positive and frictional connection is created. The material of the supporting band (3) should exhibit a coefficient of expansion which almost corresponds to that of the optical waveguide (1). As a result of the bendings of the protective sheath (2), a radial mobility of the optical waveguide (1) is additionally created, so that the latter can compensate axial changes in length of the conductor or of the cable. Inner cables, cables with small external dimensions. <IMAGE>

Abstract: A force transducer for measuring tension and compression forces, having an essentially hollow bending body (39) which can be subjected to bending stress, the first end area of which can be fixed and into the second, free end area of which the force to be measured can be introduced at right angles to the longitudinal axis (40) of the bending body (39), and a measuring rod (76) which is rigidly connected to the bending body (39) in its second end area, extends freely into the interior of the bending body and carries at its free end at least one transmitter element (98) which faces at least one receiver element arranged in a fixed position, is to be constructed in such a way that as high a measuring sensitivity as possible appears. This is achieved by the bending body (39) having a relatively low bending resistance in the area in which the force is introduced, and by the bending resistance increasing towards the side of the fixed area. If the measuring sensitivity is only to be high for forces which lie in a preferred plane, the bending body (39) has a preferred direction with relatively low bending resistance. This directional selectivity can be further increased by a preferred arrangement of a magnet as transmitter element and a Hall sensor as receiver element.
